DEFINITION

Classification: 264/165

(under the class definition) Processes which are directed to the molding of a continuous, running or indefinite length body of which at least one molded element or component thereof is unitary in nature as is formed by an uninterrupted molding step.

(1) Note. Processes relating to forming of plural finite elements and combining these elements mechanically to each other to form a running length article, e.g., a chain or other mechanically interlocked article consisting of plural parts are classified elsewhere, see the note to subclass 242 below.

(2) Note. Processes wherein a continuous article of varying composition is produced by intermittent charges of molding material of varying composition in the forming device are included herein.

(3) Note. Where layered, stratified or plural element containing indefinite or continuous articles are produced, at least one element, layer or stratum must be unitary in structure as set out in the definition or (2) Note above.

(4) Note. The final article produced need not be of indefinite length, for example, forming a thread and winding the thread into a finite article is included here.

(5) Note. The line between this class (264) and Classes 8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers, and 427 Coating Processes, in regard to the fluid treatment of coagulated, extruded or otherwise shaped plastic materials is that fluid treatments of the formed structures, whether previously dried or not, as well as processes which recite broadly the mere fact of forming (without stating any significant forming step as would be included in this class under the definitions) combined with a significant subsequent fluid treatment are placed in either of Classes 8 or 427, in accordance with the line existing therebetween and set forth in the reference to Class 8 in the class definition of Class 427. See also the definitions to this class (264), and see the notes and search notes to subclasses 129, 188, 195, 196, 232, and 340 of this class (264). SEE OR SEARCH THIS CLASS, SUBCLASS:

47, for continuous article formation combined with pore forming.

70, for processes of forming indefinite length article including a vibratory step.

73, for producing indefinite length article of a random or variegated color.

99, for processes wherein pneumatic pressure is applied to the inside of a continuously extruded hollow article.

145, for continuous formation combined with cutting.

242, for processes of forming composite plural part or multilayered articles wherein said parts are joined for relative movement, e.g., chain or interlock effect.
